A scratch build twin.
I have seen these flying out of Liverpool Airport and at any altitude the wings look like pencils!
It seems like a good subject for a really lightweight design and with that tiny wing area it would have to be as a park flyer.

Apart from the challenge of building the long fuselage it has some features that would help the build.
The wing is mounted completely above the fuselage 'tube' so structurally easier to do.
The engine nacelles are huge so no problem fitting the ESC and flight battery in each side.
Although a 6 blade prop is really too difficult however even a 3 blade would be huge.

So a hand launch, belly land all Depron twin.
That's about as far as I have got. The real question is could I possibly finish it by 15th Sept?
We shall see
